Document-level recommendations

[reckart]

I also have a similar use-case for document classification with multi-label, e.g. keyphrase extraction/generation. I would also like to use external recommeder to perform some active learning thanks to some unsupervised model at the beginning, which would help build our dataset. (or import some existing one). But I didn't find a way to be able to configure such external recommender. I think it would also be very helpful to have this kind of feature. In any case, thanks for this wonderful tool!
